Patent AT-E3105-T1 (AT)
IPC: B25D11/00
Filed: 1979-12-14
Granted: 1983-05-15
Abstract: Hammertool with a reciprocating piston member (35) slideably positioned in a barrel (27) and moving between a forward limit position and a rearward limit position. An air passageway (31) open to air is formed in the barrel (27) and a first passageway (43) and a second passageway (41) are formed in the piston member (35). In the operational mode, a ram (54) and the barrel (27) coact to alternately seal and expose an enclosure (73) to the outside air through the first passageway (43) and air passageway (31) whereby the ram (54) is urged axially toward or away from the tool bit through the pressure differentials established thereby in the enclosure (73). The second passageway (41) is formed in a forward portion (39) and is spaced a predetermined distance away from the first passageway (43) such that the second passageway (41) communicates with the air passageway (31) to ensure that air is supplied to the enclosure (73) during the course of the movement of the piston member (35) from said forward limit position to said rearward limit position when the hammer tool is operating in the idle mode. In this way, the ram (54) remains inactive when the tool bit is removed or when the tool is lifted from the work surface because no significant pressure differentials are developed in the enclosure (73).

Abstract: A fleece is employed for the distribution of casting resin over a component surface to be sealed. Prior to the introduction of the casting resin, pressure is applied on the fleece with a heated stamp in order to smoothen the fleece. Through increased temperature of the stamp, or through a solvent, the fleece can be readily cemented together with the component surface. It is thus ensured that the fleece rests uniformly on the entire component surface to promote a favorable distribution of the casting resin.

Abstract: Electronic printer apparatus in which the intensity of the beam of a cathode-ray tube is controlled during successive beam sweeps to display and project onto a rotating electrostatically-charged surface an image of successive slices through a row of characters to be printed, the latent line images thus formed being then converted to a toner image for subsequent transfer to a page of paper. Digital information bits organized in bytes and representing slices through each character are stored in respective areas of a permanent memory storage device. The appropriate slices of the characters are accessed in response to character-representing input signals, and are read out serially to control the beam intensity during each sweep and thus display, along the sweep, the desired slice through the row of characters. The stored bits for each character slice are organized into various integral numbers of x-bit and y-bit bytes, preferably 8-bit and 6-bit bytes, the number of bytes of each type for each character slice depending on the bit width of the corresponding character cell; there are no extra or left-over bits beyond these included in the two types of bytes. The so-stored bytes of differing bit content are accessed byte-by-byte, enabling simplification and reduced cost of the apparatus.
